12-mp7 use structure during the
california gold rush, miners sometimes
paid $10 for a glass of water. what was
the total cost if 8 miners each bought
one glass of water? how can you use a 4s
fact to find the answer?

14-higher order thinking lani said all
of the multiples of 8 are also multiples
of 2. jamila said all of the multiples
of 8 are also multiples of 4. who is
correct? explain.
